Q:17. Could you do 3d modeling on both a mac and windows computer?
Yes, we do 3D modeling on both a mac and windows computer.
Q:18. What makes 3d printing superior to other crafting techniques?
Customization is makes 3d printing superior to other crafting techniques.
Q:19. What is it called when I need to move an object in 3d?
Move command is it called when I need to move an object in 3D.
Q:20. Which axis determines if the object is 3d?
The third coordinate is often called z. The z-axis is perpendicular to both the xaxis and the y-axis.
Q:21. Is 3D modeling only used for 3D printing?
basic principles of 3D modeling across all design verticals remain the same, there are a few aspects of designing that need to be considered while modeling for 3D printing.
